To arrange the numbers 23, 76, 18, and 910 from least to greatest, we need to compare their values:
- 18
- 23
- 76
- 910
Starting with the smallest number, we see that 18 is less than 23, which is less than 76, and finally, 910, which is much larger than the other three. So, when we line them up in order from least to greatest, we have:
- 18
- 23
- 76
- 910
Thus, the proper order from least to greatest is: 18, 23, 76, 910.
